Question

the area of sqaure are the same . The perimeter is 60 cm. If the length of the rectangle is 9cm , find its breadth and perimeter​

Answer 1

Answer:
Breadth of the rectangle=15 cm
Perimeter of the rectangle=48 cm

Step-by-step explanation:
here the area of square and rectangle is same. Means;
side²=length×breadth.

Perimeter of square=60 cm
→4s=60cm
→s=60÷4
→s=15cm

So, the side of the square is 15 cm
Then, area of the square=s²
→(15cm)²
→225 cm²

We know that the area of square is equals to the area of the rectangle.
→Area of rectangle=Area of square
→Area of rectangle=225 cm²
→l×b=225 cm²
→9cm × b=225 cm²
→b=225÷9
→b= 15cm

So the breadth of the rectangle =15cm

Perimeter of the rectangle= 2(l+b)
→2×(9+15)
→2×24
→48cm
