Answer:

20 inches

Step-by-step explanation:

<u><em>Find the distance BC</em></u>

we know that

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have

B(-3,-3),C(1,-3)

substitute

BC=\sqrt{(-3+3)^{2}+(1+3)^{2}}

BC=\sqrt{(0)^{2}+(4)^{2}}

BC=4\ units

Remember that

each unit on the grid represents 5 inches

so

Multiply the distance in units by 5

BC=4(5)=20\ in
