Use the diagram and the Pythagorean Theorem to find the EXACT area of square ABCD

Burka [1]

ANSWER

The area of square ABCD is
$25 \: square \: unit$

EXPLANATION

The area of square ABCD is the square of the length of one side.

That is the area of ABCD is |AD|²

From Pythagoras theorem,

${|AD|}^{2} = { |AG| }^{2} + { |GD| }^{2}$

We can read from the graph that, each box is one unit.

This implies that,

${|AD|}^{2} = {4}^{2} + {3}^{2}$

${|AD|}^{2} =16 + 9$

${|AD|}^{2} =25$

Therefore the area of square ABCD is 25 square units.

The correct answer is option C.

The selling price for a classic car is $12,000, which is $500 less than two times its original price. What was the original pric

Rashid [163]

Answer:$6250

Step-by-step explanation:

selling price(sp)=12000

Original price(op)=?

sp+500=2 x op

12000+500=2 x op

12500=2 x op

Divide both sides by 2

12500/2=(2 x op)/2

6250=op

Therefore original price is $6250
