Answer:
area = 50 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A =
h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here h = 4, a = 15 and b = 10, thus
A =
× 4 × (15 + 10) = 2 × 25 = 50 cm²
Answer:
72
Step-by-step explanation:

and one hundredth
A) 407 tenths

Thus decimal form of 407 tenths is 40.7.
B) 209 hundredths

Thus decimal form of 209 hundredth is 2.09.
The perimeter of the triangle will be 41ft
<h3>The perimeter of a triangle</h3>
The perimeter of a triangle is the sum of all the sides of the triangle
From the given triangle, we need to get the third sidee firse as shown:
h² = 12² + 12²
h² = 144 + 144
h² = 288
h = 17ft
Perimeter = 12 + 12 + 17
Perimeter = 41ft
Hence the perimeter of the triangle will be 41ft
