Question

Length of a rectangle is 2 less than three times its breath if the perimeter of the rectangle is 1028 M find the length and breath of the triangle

Answer 1

Answer:

length = 385m

breadth = 129m

Step-by-step explanation:

Let it's breadth be x

Therefore, length = 3x - 2

Perimeter = 1028 m

= 2(l+b) = 1028

= 2 (3x -2 + x) = 1028

= 2 × (4x - 2). = 1028

= 8x - 4 = 1028

= 8x = 1028 + 4

= 8x. = 1032

= x. = 1032÷8

= x. = 129 m

Therefore breadth = 129m

length = 3x -2

= 387-2

= 385 m
