Question

Find the perimeter and area of a rectangular piece of a land measuring 25/2 m by26/5 m.how much area of land is left unused if 4 small square flower beds of side lenth 1 m are made at the centre

Answer 1

Answer:

area of rectangle = L×B

=25/2×26/5

=65m^2

Perimeter of rectangle =2(L+B)

=2(25/2+26/5)

=35.4m

Area of square=L^2

=1^2=1m^2

4sqiare= 4×1= 4m^2

Area unused = 65m^2-4m^2

=61m^2

Answer 2

Answer:

Length of the rectangle=25/2m

Breadth of the rectangle=26/5m

Perimeter=2(l+b)

2(25/2+26/5)

2(125/10+52/10) [TAKING LCM]

2(177/10)

177/5m (or) 35.4m

Area=l x b

(25/2 x 26/5)

=65m^2

Area of one flower bed=1m x 1m [AREA OF SQUARE]=1m^2

Area of 4 flower beds=4 x 1m^2=4m^2

(65-4) m^2

=61m^2

Hope it helps...
