Two adjacent sides of rectangle are 5 x+6 and 2 x + 66. Find its area

1.	Two adjacent sides of rectangle are 5 x+6 and 2 x + 66. Find its area if its perimeter is 186 cm.
Answer» ANSWER: perimeter of RECTANGLE is =2(l+b) 2(x+6+2x+66)=186 2(3x+72)=186 3x+72=186/2 3x+72=93 3x=93-72 3x=21 x=21/3 x=7 l=7+6=13 b=2 x 7+66=14+66=80 area of rectangle=l x b =13x80 =1040 cm^2 Step-by-step EXPLANATION:

Two adjacent sides of rectangle are 5 x+6 and 2 x + 66. Find its area if its perimeter is 186 cm.

Answer»

perimeter of RECTANGLE is =2(l+b)

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

2(3x+72)=186

3x+72=186/2

3x+72=93

3x=93-72

3x=21

x=21/3

x=7

l=7+6=13

b=2 x 7+66=14+66=80

area of rectangle=l x b

=13x80

=1040 cm^2
