Question

The perimeter of a rectangle is 80x. The base is 7 times the height. In terms of x, what are the dimensions of the rectangle?

Answer 1

okay one sec i got u

Answer 2

Perimeter = 2B+2H ^ B = 7H
80X = 2(7H) + 2H
80X = 16H
10X = 2H
So,
H = 5X and B = 35X

Area of the rectangle = BH = (5X) (35X)
A = 175X^2

Answer 3

good looks bro

Answer 4

Find the area of a trapezoid in which base1 is 9 units, base2 is 7 units, and the height is 3 units.

Answer 5

dont call me bro ima chick

Answer 6

lol

Answer 7

one sec

Answer 8

oops sorry

Answer 9

area of trapezoid = [(b1+b2)h]/2

sub it in you get...

area = [(12+14)13]/2
=[26x13]/2
=338/2
=169 units square

Answer 10

its okay:)
