| 1) A rectangle has a perimeter of 112 cm. SOLUTION 1 : Step 1: Perimeter of rectangle if length is the same as breadth: 112 - 24 - 24 = 64 cm Step 2: Breadth of rectangle: 64 ÷ 4 = 16 cm Step 3: Length of rectangle: 16 + 24 = 40 cm Step 4: Area of rectangle: 40 x 16 = 640 cm2 Its area is 640 cm2. |
| 2) A rectangle has a perimeter of 84 cm. SOLUTION 1 : Step 1: Perimeter of rectangle if length is the same as breadth: 84 - 16 - 16 = 52 cm Step 2: Breadth of rectangle: 52 ÷ 4 = 13 cm Step 3: Length of rectangle: 13 + 16 = 29 cm Step 4: Area of rectangle: 29 x 13 = 377 cm2 Its area is 377 cm2. |
| 3) A rectangle has a perimeter of 232 cm. SOLUTION 1 : Step 1: Perimeter of rectangle if length is the same as breadth: 232 - 18 - 18 = 196 cm Step 2: Breadth of rectangle: 196 ÷ 4 = 49 cm Step 3: Length of rectangle: 49 + 18 = 67 cm Step 4: Area of rectangle: 67 x 49 = 3283 cm2 Its area is 3283 cm2. |
| 4) A rectangle has a perimeter of 120 cm. SOLUTION 1 : Step 1: Perimeter of rectangle if length is the same as breadth: 120 - 20 - 20 = 80 cm Step 2: Breadth of rectangle: 80 ÷ 4 = 20 cm Step 3: Length of rectangle: 20 + 20 = 40 cm Step 4: Area of rectangle: 40 x 20 = 800 cm2 Its area is 800 cm2. |
| 5) A rectangle has a perimeter of 232 cm. SOLUTION 1 : Step 1: Perimeter of rectangle if length is the same as breadth: 232 - 26 - 26 = 180 cm Step 2: Breadth of rectangle: 180 ÷ 4 = 45 cm Step 3: Length of rectangle: 45 + 26 = 71 cm Step 4: Area of rectangle: 71 x 45 = 3195 cm2 Its area is 3195 cm2. |
| 6) A rectangle has a perimeter of 180 cm. SOLUTION 1 : Step 1: Perimeter of rectangle if length is the same as breadth: 180 - 28 - 28 = 124 cm Step 2: Breadth of rectangle: 124 ÷ 4 = 31 cm Step 3: Length of rectangle: 31 + 28 = 59 cm Step 4: Area of rectangle: 59 x 31 = 1829 cm2 Its area is 1829 cm2. |
| 7) A rectangle has a perimeter of 84 cm. SOLUTION 1 : Step 1: Perimeter of rectangle if length is the same as breadth: 84 - 22 - 22 = 40 cm Step 2: Breadth of rectangle: 40 ÷ 4 = 10 cm Step 3: Length of rectangle: 10 + 22 = 32 cm Step 4: Area of rectangle: 32 x 10 = 320 cm2 Its area is 320 cm2. |
| 8) A rectangle has a perimeter of 160 cm. SOLUTION 1 : Step 1: Perimeter of rectangle if length is the same as breadth: 160 - 28 - 28 = 104 cm Step 2: Breadth of rectangle: 104 ÷ 4 = 26 cm Step 3: Length of rectangle: 26 + 28 = 54 cm Step 4: Area of rectangle: 54 x 26 = 1404 cm2 Its area is 1404 cm2. |
| 9) A rectangle has a perimeter of 88 cm. SOLUTION 1 : Step 1: Perimeter of rectangle if length is the same as breadth: 88 - 28 - 28 = 32 cm Step 2: Breadth of rectangle: 32 ÷ 4 = 8 cm Step 3: Length of rectangle: 8 + 28 = 36 cm Step 4: Area of rectangle: 36 x 8 = 288 cm2 Its area is 288 cm2. |
