Length of a rectangle is 3 in longer than the width when the perimeter is 54 inches

1 answer:

3 0

Let width be x,
Length: 3+x

P=2(l+w)
54=2(x+(x+3))
54/2=2x+3
27=2x+3
27-3=2x
24=2x
24/2=x
12=x

Therefore, the width is 12 inches and the length is (12+3)=15 inches

Hope I helped :)

Question 3 options:

Grace [21]

Answer:

Step-by-step explanation:

Given: Measure of one side of equilateral triangle = $9+3x$

Measure of another side of equilateral triangle = $5x-5$

In equilateral triangle all three sides are equal in length.Therefore,

$5x-5 =9+3x$

$5x-3x=9+5$

$2x=14$

$x=\frac{14}{2} =7$

On substituting the value of x in side of equilateral triangle,

One side of equilateral triangle = $5x-5=\left (5(7)-5 \right )=(35-5)=30$

Perimeter of equilateral triangle = 3 ( length of one side) ........( given)

perimeter of equilateral triangle = $3\times30 = 90.$
