Question

find the side of square in metre and its perimetre in metre when its area is 400 cm2​

Answer 1

area = 400 cm²

a² = 400

a =20 cm = 0.2 m

₩) perimeter = 4a = 4×20 = 80cm = 0.8 m

Answer 2

We know that side²=area of square

We know that side²=area of square Therefore side²=400cm²

We know that side²=area of square Therefore side²=400cm² side=20 cm=0.2m

We know that side²=area of square Therefore side²=400cm² side=20 cm=0.2mNow perimeter of square =4×side

We know that side²=area of square Therefore side²=400cm² side=20 cm=0.2mNow perimeter of square =4×side =4×20cm

We know that side²=area of square Therefore side²=400cm² side=20 cm=0.2mNow perimeter of square =4×side =4×20cm =80cm=0.8 m

We know that side²=area of square Therefore side²=400cm² side=20 cm=0.2mNow perimeter of square =4×side =4×20cm =80cm=0.8 mPlease mark as brilliant.
