Question

If the perimeter of the triangle is 28 and lenth x

Answer 1

Answer:

perimeter =28 m /cm

length=x

breadth=also be x

then; p =2×(l+b) =28

2×(x+x)=28

Step-by-step explanation:

2x+2x=28

4x=28

x=28/4

x=7

So; x=7m./cm.

therefore; l=7m/cm

b=7m/cm

correction; 2×(7+7)=28

2×14=28

28=28
