Question

the perimeter of a triangle is 40 m its length is 4m less than the five time of his breath find the dimension of the rectangle?

Answer 1

Answer:

Step-by-step explanation:

Perimeter=2(Length+Breath);

Perimeter=40;

Length=5B-4;

So

40=2(5B-4+B);

20=6B-4;

24=6B;

B=24/6=4m;

Length=5B-4=5*4-4=20-4=16m;
