have more area?

Answer 1

this is ans of this question

Answer 2

Given:  

The length of a rectangular field is 8m and breadth is 2m.

To Find:

If a square field has the same perimeter .Find which field have more area?

Solution:

Length of rectangular field = 8 m  

Breadth of rectangular field = 2 m  

Perimeter of rectangular field = 2(l+b)=2(8+2)=20 m  

We are given that a square field has the same perimeter

So, Perimeter of square = $4 \times Side$

So, $4 \times Side = 20$

Side = $\frac{20}{4}$

Side = 5  

Area of square field = $Side^2 = 5^2 = 25 sq.m.$

Area of rectangular field = $Length \times Breadth= 8 \times 2 = 16 sq.m.$

Difference between area = 25-16 = 9 sq.m.

Hence The area of square field is more than area of rectangular field by 9 sq.m.
