Question

What is x?

fast as fast you can

Answer 1

2(l+b)
2(5x+6)+2x+66)=186
2(7x+72=186
7x+72=186÷2
7x = 93-72
7x= 21
x = 21÷7
x = 3

Answer 2

Hi friend,

Perimeter of rectangle = 186 cm

Length = 5x+6

Breadth = 2x+66

Perimeter of rectangle = 186

2(length + breadth) = 186

2(5x+6+2x+66) = 186

10x+12+4x+132 = 186

14x+144 = 186

14x = 186-144

14x = 42

x = 42/14

x = 3

Length = 5(3)+6 = 15+6 = 21

Breadth = 2(3)+66 = 6+66 = 72

Hope it helps
