The perimeter of a rectangle is 8(2x + 1) inches. The length of the sides of a rectangle are 3x + 4 inches and 4x + 3 inches. Write and solve an equation to find the length of each side of the rectangle.
8(2x+1)=2(3x+4) + 2(4x+3)
16x+8=6x+8+8x+6
16x+8=14x+14
2x=6
X=3
now just replace X with 3 to find the length and width
Answer:
Length of rectangle=\(3(3)+4=13\)
Width of rectangle=\(4(3)+3=15\)
Step-by-step explanation:
We are given that
Perimeter of rectangle=\(8(2x+1)\)
Length of sides of rectangle=\(3x+4\)
Width of rectangle=\(4x+3\)
We have to solve the equation and find the length of each side of rectangle
We know that perimeter of rectangle=\(2(L+B)\)
Substitute the values then we get
\(8(2x+1)=2(3x+4+4x+3)\)
\(16x+8=14x+14\)
\(16x-14x=14-8\)
\(2x=6\)
\(x=\frac{6}{2}=3\)
Substitute the value of x then we get
Length of rectangle=\(3(3)+4=13\)
Width of rectangle=\(4(3)+3=15\)
