Answer:

width = 10 cm

length = 37 cm

perimeter = 94 cm

area = 370 cm^2

Step-by-step explanation:

Perimeter = 2(length + width)

x is width, then length is 3x + 7

so 2(x + 3x + 7) = 94

4x + 7 = 47

4x = 40

x = 10

length = 3(10) + 7 = 37

Find the measure of each angle (in degrees) of
d1i1m1o1n [39]

Answer:

∠A = 88°

∠B = 92°

∠C = 88°

∠D = 92°

Step-by-step explanation:

∠A + ∠B = 180°

(2x + 4) + (3x - 34) = 180

reduce:

5x - 30 = 180

5x = 210

x = 42

∠A = 2(42) + 4 = 88°

∠B = 3(42) -34 = 92°

∠C = ∠A = 88°

∠D = ∠B = 92°
