Question

A rectangle Perimeter is 48m,if its breadth is 4m find its area​

Answer 1

Answer:

80m²

Step-by-step explanation:

Given: b= 4m , P= 48m

P= 2(l+b)

=> 48= 2(l+4)

=> l+4= 24

=> l= 20

So area = l*b = 20*4 = 80m²

Answer 2

Answer:

perimeter=48m

breadth=4m

length=?

area=?

Step-by-step explanation:

perimeter of rectangle = 2( length+breadth)

48 = 2(l+4)

48= 2×4l

48 = 8l

48/8 = l

6= l

area of rectangle = l× b

= 8×4

= 32 m²
