Question

An advertising banner has four sections as modeled below. Two sections are congruent trapezoids and two sections are congruent right triangles.

Answer 1

6 m²

Explanation:

Since we are told that there are two congruent trapezoid, it means that they will have same base of 1m.

his Means the total base of the entire triangle will be;

Base = 1 + 1¾ + 1 + 1¾ = 5.5 m

Height of main triangle = 2 m

Now you have

Area = ½ × 5.5 × 2 = 5.5 m²

We are looking for best estimate, so if you round 5.5 now remember 5 or more raise the score 4 or less let it rest leaving you with 6 m².

Answer 2

Complete question is;

An advertising banner has four sections, as modeled in the attached image. Two sections are congruent trapezoids, and two sections are congruent right triangles. Which measurement is the best estimate of the area of the banner in square meters?

Answer:

6 m²

Explanation:

Since we are told that there are two congruent trapezoid, it means that they will have same base of 1m.

This Means the total base of the entire triangle will be;

Base = 1 + 1¾ + 1 + 1¾ = 5.5 m

Height of main triangle = 2 m

Thus,

Area = ½ × 5.5 × 2 = 5.5 m²

We are looking for best estimate, so let's approximate to the nearest whole number to get 6 m²
