Answer:
169 cm²
Step-by-step explanation:
Recall that the area of the largest square is |PR|²
Also recall from Pythagoras Theorem that:
|PQ|² +|QR|² =|PR|² ---->1
Also we have that the sum of the areas of the three squares is 338 square centimeters.
This implies that:
|PQ|² +|QR|² +|PR|²=338---->2
Put equation (1) into (2)
|PR|²+|PR|²=338
Simplify to get:
2|PR|²=338
Divide both sides by 2 to get:
|PR|²=338
|PR|²=169
<span>1) The percentage amount give as a check per week is 25%. Since 75% of the pay is done via direct deposit then we can conclude based on the info given to us here is that the rest 100-75 = 25% is given by check.
2) The percentage amount deposited in the savings account each month is 37.5%. Since we know that 75% direct deposited and that 50% of that amount goes into savings, we can conclude the amount that goes to savings by multiplying 75 by 50% which is 37.5%</span>
“A number” can be denoted as x. The quotient of x and 3 would be written as x/3. Since this is equal to -8, then we just write:
x/3 = -8

So you want to start by finding the area of the big square.
We know the width of the big square is 60cm. The length of the big square is

Now let’s find the little square inside the bigger square. We see from the picture that the width is 34 and the length is 24cm. Using the same formula, we can find the area of the little square.
