A rectangle has an area of 235.2m2.
One of the sides is 2.8m in length.
Work out the perimeter of the rectangle.

173.6 m

Step-by-step explanation:

Perimeter of rectangle= 2* length + 2* width

Area = 235.2m²

Length= 2.8

Area of rectangle: length*width

So: 2.8*width= 235.2m²

width= 235.2/2.8= 84

Use the formula for perimeter of rectangle

So: 84*2 + 2.8*2

Perimeter= 173.6m

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
