Question

. A path 1.5 m wide is built along the border inside a square park of side 30 m Find the cost of
covering the remaining portion by grass at the rate of Rs. 1.50 per square meter
20. The area of a square and a rectangle are equal. If the side of the square is 40 cm and the breadth of
find the length of the restangle. Also, find the perimeter of the rectangle​

Answer 1

Answer: Let ABCD, the square garden of side= 30 m.

PQRS is the region inside the garden.

so,

PQ = (30 -1-1 ) = 28 m

also

PS = ( 30 – 1 – 1 ) = 28 m

(i) Area of the path = Area of ABCD – Area of PQRS

= [( 30 x 30) – (28 x 28)]

= 900 – 784

= 116 sq.m

(ii) Area of the remaining portion in which the grass is planted = Area of square PQRS

= 28 x 28

= 784 sq.m

cost of planting the grass in the region PQRS =  area x cost = 764 x 40

=31,360
