Question

Two squares of side 2 cm are cut out of a rectangle
10 cm by 5 cm. Find the perimeter of the remaining
figure​

Answer 1

Given :

• Two squares of side 2 cm are cut out of a rectangle 10 cm by 5 cm.

To find :

• The perimeter of the remaining  figure ?

Solution :

• The length of the rectangle is 10 cm.

• The breadth of the rectangle is 5 cm.

Perimeter of the rectangle is = 2(l+b)

P=2(10+5)

P=2(15)

P=30 cm

Side of first square is 2 cm.

Perimeter of square is

P=4s

P=4(2)=8 cm

Similarly, the perimeter of the second square is 8 cm.

Total perimeter of both square = 8+8=16 cm

Perimeter remaining = Perimeter of rectangle - Perimeter of square

Perimeter remaining = 30-16

Perimeter remaining = 14 cm
