Question

the length of rectangle is 5 cm more than its breadth if the perimeter of the rectangle is 50 cm then what is the area

Answer 1

Answer:

75 sq cm

Step-by-step explanation:

Let us take the length as L + 5 and the breadth as L.

Perimeter

= 2 (length + breadth)

= 2 ( L + 5 + L )

= 2 ( 2L + 5 )

=4L + 10

4L + 10 = 50

4L = 40

L = 10

Length = 15, Breadth = 5

Area = L×B

= 15 * 5

=75

Answer 2

let length be x

then breadth is x-5

A/q

2(x+x-5)=50

2(2x-5)=50

4x-10=50

4x=50+10

4x=60

x=60÷5

x=12

So length is 12

breadth is 12-5=7

So area =12×7= 84
