Question

the length and breadth of a rectangle are in the ratio 4:1. find the area of rectangle if the length is 64 m​

Answer 1

Answer:

length and breadth 4:1

Step-by-step explanation:

length 4x=64 ( given)

breadth 5x

Area=length * breadth

a=64x*5x

Answer 2

Answer:let the length of rectangle,l be 4x m

Accordingly, breadth of rectangle,b =x m

Given length of rectangle= 64

ar(rectangle)= l×b

Equation becomes:-

4x × x= 64× x

4x=64 × x / x

4x= 64 × 1

x= 64 / 4 =16 m

Now, we have breadth,b = x = 16m

Length,l =64 m

Ar(rect)= lb= 16m×64m

= 1024m²
