on three sides with length 40 m, 20 m and 20 m. Find
the cost of fencing at the rate of 15 per m. Also,
find the area of her garden.​

Answer 1

Answer:

First we will find the area of the three sides by multiplying 40m × 20m = 800m, then divide it by 2 like 800 ÷ 2 = 400 sq m. So the area will come 400 sq m. Then we will multiply 400 sq m × 15 = Rs.600 for finding the cost of fencing.

( So, The cost of fencing will be Rs.600 and area will be 400 sq m ).
