Question

Find the length of a rectangle. If breath is 5cm and perimeter is 26 cm?

Answer 1

We know that,

P = 2(l + b)

2(l + 5) = 26

l + 5 = 26/2

l + 5 = 13

l = 13-5 = 8

Length = 8 cm

Answer 2

Answer:

Step-by-step explanation:

Let the length of the rectangle be =xcm

Breadth of the triangle =5cm

Perimeter of triangle =26 cm

2(l+b) =26

2(x+5)=26

2x+10=26

2x=26-10

2x=16

X=16/2

X=8

hence the length of the triangle =8cm
