is a rectangle bisected by the diagonal forming two congruent right triangles, so AD = BC and AB = CD

Area = 1/2 b * h

Area =1/2 7 * 4

Area = 14 in²

Steps:

So we have 7 in. and 4 in. so we just will mutilply It, So what we do here Is mutilply so we will do 7 x 4 = 28

So we have 28 then we mutilpy all of chocies to see which one Is 28.

A rectangle bisected by the diagonal forming two congruent right triangles, so AD = BC and AB = CD

11 x 2=22 ❌ Not 28

14 x 2 = 28 ✅ Is 28

22 x 2 = 44 ❌ Not 28

28 x 2 = 56 ❌ Not 28

Step 2:

A rectangle bisected by the diagonal forming two congruent right triangles, so AD = BC and AB = CD

Area = 1/2 b * h ❌

Area = 3.5 * 4 ❌

Area = 3.5 * 4 ❌

Area = 14 in²
