Question

a square and a parallelogram have the same area if a side of a square is 40 and the height of the parallelogram is 20 metres find the base of the parallelogram​

Answer 1

Answer:

area of square =a^2

therefore 40*40=1600

area of parallelogram is equal to the area of the square so

b*h=1600

b*20=1600

b=1600/20

therefore b=80 metres

Answer 2

Answer:

Base of parallelogram is 80m

Step-by-step explanation:

Area(square) =area(parallelogram)

Side x side = height x base

40 x 40 = 20 x base

1600 = 20 x base

1600÷20 = base

80 = base

Hence base of parallelogram is 80 m
