Question

the length of a triangles 20 cm more than its breadth. If the perimeter is 100 cm find the dimension of rectangle

Answer 1

Answer:

15 by 35 cm

Step-by-step explanation:

let say breadth = B

length = B +20

perimeter = 2*(length + breadth)

100 = 2 * (B +20 + B)

50 = 2B +20

2B = 30

B = 15

breadth = 15 cm

length = 15+20 = 35 cm
