Question 8
Shyaivi has a rectangular garden of length 95 metre and breadth 80 metre. He wants to plant trees by digging 5 metre broad area outside the garden. Find out the area in which he will plant trees.
Answers
The area of the rectangular garden in which Shyaivi will plant trees is 1850 m².
Step-by-step explanation:
The dimension of the rectangular garden:
Length, l = 95 m
Breadth, b = 80 m
∴ Area of the rectangular garden = l * b = 95 * 80 = 7600 m²
It is given that an area of 5 m broad outside the garden in order to plant the trees
So, the dimension of the garden + the outside area for planting trees:
New length = 95 + (5*2) = 105 m
New breadth = 80 + (5*2) = 90 m
∴ Area of the rectangular garden including the broad area outside the garden,
= new length * new breadth
= 105 * 90
= 9450 m²
Thus,
The area in which Shyaivi will plant trees is given by,
= [Area of the rectangular garden including the broad area outside the garden] – [Area of the rectangular garden]
= 9450 – 7600
= 1850 m²
