Question

Q. A rectangular garden is 100 m long and 80 m broad. Find:

(i). the area of the garden
(ii). the perimeter of the garden
(iii). the cost of fencing the garden at the rate of Rs. 8 per metre.​

Answer 1

Answer:

Step-by-step explanation: i) Area = L*B

So, 100 * 80 = 8000m sq.

ii) Than It has ask for perimeter so perimeter 2(l+b)

= 2(100+80)

=2*180

=360m

iii) cost of fencing is 360 * 8 = Rs. 2880

Answer 2

Ans. Length of the garden (l) = 100m

Breadth of the garden (b) = 80 m

(i) Area of the garden = lb

= 100×80

Area of the garden = 8000 m²

(ii) Perimeter of the garden = 2(l+b)

= 2(100+80)

= 2×180

Perimeter of the garden = 360 m

(iii) Rate of fencing = ₹8 per metre

Perimeter = 360 m

Cost of fencing = 8×360

Cost of fencing the garden = ₹2880
