Answer:
answer :36
Step-by-step explanation:
opp exterior angles are equal............
7/12*6/14
7*6=42
12*14=168
=42/168
=0.25 =1/4
All together they peeled 20
J:jacob
G:grandma
4J=G. Since she peeled 4 times as he did
4J=16
J=4
So jacob peeled 4 potatoes
All in all:J+G
4+16=20
Half the area is 6000.
let x be the width of the walk so the inner rectangle has a length of 150-2x and width 80-2x and hence its area is (150-2x)(80-2x) which is equal to 6000.
so now we have an equation in terms of x which reduces to a quadratic and we solve for x
