We can do several rectangles and 2 triangles
the easiest way is to find the area of the big rectangle minus the cut off pices

a. 1 big rectangle-2 corner triangles
b. area rectangle=lenght times height=24 times 11=264 square feet
the triangles
bottom left one is height 11-7=4 and base 24-14=10
bottom left=1/2 times 4 times 10=20
top right is 24-20 by 11-6 or 4 by 5, area=1/2 times 4 times 5=10

so
rectangle-triangles=264-(20+10)=264-30=234 square feet

Everything in a store is discounted by 25%. What is the sale price of a clock with a regular price of $24.60?

Lelechka [254]

Answer:

$24.35

Step-by-step explanation:

sale price⇒ total price-discount price

s.p=$24.60-25/100 ∴25%⇒25/100

s.p⇒$2460/100-25/100 ∴24.60⇒2460/100

s.p⇒$24.35

⇒$24.35

What is the approximate area of a circle with a radius of 10 in?

yKpoI14uk [10]

<em></em> $\huge\boxed{\textsf{A.}\ 78.5\ \text{in}^2}$

<em></em>

<em>Correction to your question text: diameter, not radius.</em>

The area of a circle is given by:

$A=\pi r^2$

The radius is half of the diameter.

$A=\pi\cdot\left(\dfrac{10}{2}\right)^2$

Substitute and solve.

$\begin{aligned}A&=\pi\cdot\left(\frac{10}{2}\right)^2\\&=\pi\cdot5^2\\&=\pi\cdot25\\&\approx\boxed{78.5}\end{aligned}$
