What is the area of the figure:

Leni [432]

A 45 45 90 triangle
so a = b
a^2 + b^2 = c^2
a^2 + a^2 = c^2
2a^2 = c^2
2a^2 = 24^2
 2a^2 = 576
a^2 = 288
a = 12√2
b = a = 12√2

Area of triangle:
= 1/2 (12√2)(12√2)
= 1/2(288)
= 144

answer
Area = 144 ft^2

Which equation can be used to calculate the area of the shaded triangle in the figure below?

lozanna [386]

Answer:

Step-by-step explanation:

The area (A) of a triangle is calculated using the formula

A = $\frac{1}{2}$ bh ( b is the base and h the perpendicular height )

here b = 14 and h = 4, hence

A = $\frac{1}{2}$ (14 × 4) = 28
