Question

ii] Solve the following. (ANY TWO)
a] Find the area of circle having radius = 7cm. (T1 = 22)
b] Find the area of square if one of the side measures 12cm.
c] Find the area of rectangle if length = 15cm and breadth = 10cm.​

Answer 1

a) Area of Circle= pie(π)x(Radius)^2
Since Radius(r)= 7cm
Therefore,
Area= 22/7x7
Cancelling 7 and 7
Area =22cm^2....Answer

b) Since area of Square=(side)^2
Therefore,
If Side=12cm
Area= (12)^2
= 144cm^2 ....Answer

c) Area of Rectangle= LengthxBreadth
Since,
L=15cm, B=10cm
Therefore,
Area= 15x10
= 150cm^2 ....Answer
