The total area of square TUVW is 160 meters.
<h3>Find out the sides of PQRS:</h3>
Total area: side x side
256 m = side x side
side = √ 256
side= 16 m
This means PQ, QR, RS, SP = 16 m
<h3>Find out the area of one triangle:</h3>
Area: 1/2 x base x height
Let's find out the area of the triangle UVR although all triangles are the same.
Base: 4 meters
Height:
RQ= 16
QU= 4
16-4 = 12
Area: 1/2 x 4 x 12 = 24
<h3>Find the total area of the triangles:</h3>
24 x 4 = 96
Finally, find out the total area of the grey square:
Total area of the grey square = Total area of the white square - area of the triangles
Total area = 256 - 96
Total area= 160

Answer:
x = 1
y = 3
Step-by-step explanation:
2x + 1 = y ------- eqn (1)
2y = 6--------eqn (2)
from eqn(2)
2y = 6
y = 3
when you divide 6 by 2y
substitute y = 3 into eqn (1)
2x + 1 = y
2x + 1 = 3
2x = 3-1
2x = 2
therefore
x = 1
The number of pounds of copper in 120 pounds of brass is = 78 pounds of copper
<h3>Calculation of number of pounds of copper</h3>
The percentage of copper in the brass = 65%
Therefore the quantity of copper in the brass = 65/100= 0.65 pounds
This means that 1 pound brass contains = 0.65 pounds of copper
The quantity of copper in 120 pounds of brass = 120 * 0.65
= 78 pounds of copper.
