Answer:_______________

The area of a parallelogram whose base is14 cm and height is 4 cm is

1) 54
2) 48
3) 56
4) 62

Answer: 3

SOLUTION 1 :

Given :

b = 14cm

h = 4cm

Area = b x h

= 14 x 4

= 56 cm²

The base of a parallelogram whose area is 298 cm² and the height 6 cm is

1) 44.67
2) 49.67
3) 58.67
4) 53.67

Answer: 2

SOLUTION 1 :

Given :

Area =298cm²

height = 6cm

Area of the parallelogram = b x h

298 /6 = b

49.67 cm = b
