a garden is 90m long and 50m wide a path of 5m of width is built outside and around it. find the area of the path |
|
Answer» Area of original GARDEN =90×75=6750 m 2
After path is added AROUND rectangle, new length =90+2×5=100 m New breadth =75+2×5=85 m Area of rectangle with path =100×85=8500 m 2
So, Area of path = Area of rectangle with path − Area of rectangle WITHOUT path Area of path =8500−6750 =1750 m 2
We know, 1 m 2 =0.0001 hectare So, 6750 m 2 =6750×0.0001 =0.675 hectare Hence area of ground =6750 m 2 =0.675 hectares solution |

A rectangular plot is 160m2 in area. If its length is 16m, find perimeter of the |
Answer» SOLUTION:-━━━━━━━━━━━━━━━━━━━━━━━━━━ ➝ Here, the question has given US the area of a rectangular plot that is 160 m² and length that is 16 m respectively. Now, the question has asked us to FIND the perimeter of the given rectangle. First of all we will find the breadth. We simply have to apply the formula of area of rectangle to find the breadth and then after we NEED to apply the formula of perimeter of rectangle and we will get our answer. ANSWER:-☆ Breadth of the rectangle = 10 cm ☆ Perimeter of the rectangle = 52 cm GIVEN:-↣ Length of the rectangle = 16 m ↣ Area of the rectangle = 160 m² FIND:-➱ Breadth of the rectangle = ? ➱ Perimeter of the rectangle = ? FORMULAE:-➮ Area of rectangle = (L × B) [To find the breadth] ➮ Perimeter of rectangle = 2(L + B) [To find the perimeter] Where,
SOLVING BY APPLYING THE FORMULA:-
☞ 160 = 16 × B [Finding Breadth] ☞ Taking 16 to LHS. ☞ 160 / 16 = B ☞ 10 = B ☞ B = 10 m Hence, we got the breadth of the rectangle. Breadth of the rectangle is 10 m.
☞ Perimeter = 2(16 m + 10 m) ☞ Perimeter = 2 × 26 m ☞ Perimeter = 2 × 26 m = 52 m ☞ Perimeter = 52 m Hence, we got the perimeter of the rectangle. Perimeter of the rectangle is 52 m. ━━━━━━━━━━━━━━━━━━━━━━━━━━ |
