Rosie is going to plant a garden along the edges of her rectangular backyard. The length of her backyard is 7 feet more than 4 times the width. The width is unknown, and can be represented by w. If the perimeter is 644 feet, what is the LENGTH and the WIDTH of rosies backyard?

yes daddy harder daddy harder

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
