10. The length of a rectangular field is 10m more than its breadth. If the
perimeter is 80m, find its length and breadth.

length = 15

breadth = 25

Step-by-step explanation:

length = breadth + 10

let length be x

length = x

breadth = x + 10

perimeter = 2(length) + 2(breadth)

80 = 2(x) + 2(x + 10)

80 = 2x + 2x + 20

80 = 4x + 20

80 - 20 = 4x

60 = 4x

15 = x

length = x = 15

breadth = x + 10 = 25

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis
