Answer:
1.
Given :
- Length of 11 cm
- Width of 7 cm
to find :
- the perimeter of the chocolate
solution :
we all know,
- P = 2(l + w)
according to the question :
- P = 2(l + w)
- P = 2(11 + 7) = 2·(11 + 7) = 36
therefore,
- The perimeter of the chocolate is 36 cm.
2.
Given :
- length of 3 m
- width of 5 m
To find :
- the distance covered by the toy car
Solution :
- (L + W) x 2 = ?
- (3 + 5) x 2 = 8x2 = ?
- (3 + 5) x 2 = 8x2 = 16 m
According to the Question :
- 16 × 5 = 80 m
therefore,
- the distance covered by the toy car is 80 m.
3.
Given :
- Side of triangle is 20 cm.
- base of triangle is 32 cm.
- side of triangle is 50 cm.
To find :
- the perimeter of the triangle
Solution :
- Formula for getting perimeter of the triangle is
- P = a + b + c
- P = 20 + 32 + 50
- P = 20 + 32 + 50 = 102 cm
therefore,
- the perimeter of the triangle is 102 cm.
