Step-by-step explanation:
area ofQXRY = area of PQRS- area of PXYS
= 84 - 21
area of QXRY = 63 cm²
Now
In
QXRY
area of rectangle = l×b
= 9cm × a
or, 63 =9a
so, a = 7 cm
Now
for PXYS
Area of rectangle = l×b
21 = a×b
because QR = PS = a cm (opposite sides of rectanhle are equal)
or, 21=7b
so, b = 3cm
so,
a= 7cm
b= 3cm
4 1/2 times 2 equals to 9.
it is the same as 4 1/2 plus 4 1/2 and 4 plus 4 is 8 and 1/2 plus 1/2 is 1 and 8 plus 1 is 9
answer is 9
If <5=42 you multiply 5 by 8.4=42
so m <4 is going to be 33.6
4X8.4=33.6
easy fist of all determine four points x and y then divide xby y and sope you can get
15/2 = $7.5 per hour
7.5 times 5 = $37.50 earned in 5 hours
