Answer:
Area of trapezoid = 21 cm²
Step-by-step explanation:
Given:
Length of rectangular shape = 4 cm
Width of rectangular shape = 3 cm
Base of triangle = 3 cm
Number of triangle = 3 cm
Find:
Area of trapezoid
Computation:
Area of trapezoid = Area of middle rectangle + Number of triangle[Area of triangle]
Area of trapezoid = [l x b] + 2[(1/2)(b)(h)]
Area of trapezoid = [4 x 3] + 2[(1/2)(3)(3)]
Area of trapezoid = 12 + 9
Area of trapezoid = 21 cm²
Answer:
C.
Step-by-step explanation:
In total, Sophie needs $230.40.
Let's form an equation. 230.40 = 12.80x
You'll need to divide both sides by 12.80 to get the variable, x, by itself.
18 = x
Therefore the answer is C.
These triangles are congruent because of SAS so therefore 3x-5 =2x+1 and x=6
