Answer 1

Question:

The length of a rectangle is 40 cm and perimeter is 110cm .Find out breadth and area of rectangle. ​

Given:

Length of the rectangle = 40 cm

Perimeter of the rectangle = 110 cm

To Find:

Breadth and Area of the rectangle

Formulas Used:

• $Perimeter=2(l+b)$

• $Area=l\times b$

Solution:

$Perimeter=2(l+b)\\\\\\P=2(l+b)\\\\\\110=2(40+b)\\\\\\110=80+2b\\\\\\80+2b=110\\\\\\2b=110-80\\\\\\2b=30\\\\\\b=\frac{30}{2}\\\\\\b=60cm$

$Area=l\times b\\\\\\A=40\times15\\\\\\A=600cm^2$

Answer:

$\boxed{\textsf{Breadth=15cm}}$

$\boxed{\textsf{Area=600cm}^2}$

Answer 2

breath is equal to 15 CM and area is equal to 2400 CM square
