Question

DeShawn is designing a picture frame. He plots the frame on the coordinate grid below.

Answer 1

Answer:

20 inches

Step-by-step explanation:

Find the distance BC

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

$BC=4(5)=20\ in$
