Answer: YES

REASON: Since a rectangle is made of two right triangles then a rectangle inscribed in a circle must have its diagonal as the diameter of the circle.

What is the area, in square inches, of the rectangle? Show your work!!

erma4kov [3.2K]

Answer:

$\huge\boxed{\sf 7 \frac{13}{20} \ in. ^2}$

Step-by-step explanation:

Length of the rectangle = $\displaystyle 2 \frac{1}{4} = \frac{9}{4} \ in.$

Width of the rectangle = $\displaystyle 3 \frac{2}{5} = \frac{17}{5} \ in.$

Area of the rectangle:

= Length × Width

$\displaystyle = \frac{9}{4} \times \frac{17}{5} \\\\= \frac{9 \times 17}{4 \times 5} \\\\= \frac{153}{20} \\\\= 7 \frac{13}{20} \ in.^2\\\\\rule[225]{225}{2}$

Q.Take out the area of the trapezium. Parallel sides-15,23 Non parallel sides-10,8

Dmitriy789 [7]

Answer:

Step-by-step explanation:

Area of a trapezium is the average of the parallel sides times the distance between them.

If we subtract 15 units from each of the parallel sides, we end up with a triangle that has two sides of 8 units and one of 10 units. One of the 8 unit sides is the base and we need to find the height h which is perpendicular to this base.

Let the base be split into two segments, call one A, the other will be 8 - A

From Pythagoras.

10² - A² = h² = 8² - (8 - A)²

10² - A² = 8² - (8 - A)²

100 - A² = 64 - (64 - 16A + A²)

100 - A² = 64 - 64 + 16A - A²

100 = 16A

A = 6.25

h = √(10² - 6.25²)

h = √60.9375

A = ½(15 + 23)√60.9375

A = 148.31870246... ≈ 148.3 cm²
