The ratio of 4 to 8 simplifies to 1:2. X will therefore be 3/2, as 3/2:3 simplifies to 1/2 (3 = 6/2).
Answer:
Area = 55 cm2
Step-by-step explanation:
It the base of the parallelogram was 9 centimeters and increased by 2, the new base has 9 + 2 = 11 centimeters.
It the height of the parallelogram was 4 centimeters and increased by 1, the new base has 4 + 1 = 5 centimeters.
Now, we can calculate the area of the parallelogram using the formula:
A = b * h
Where A is the area, b is the base and h is the height. So:
A = 11 * 5 = 55 cm2
I think for the first one you do 8 times 9 and then 5 times 5 and add them together, I’m not sure though because I learned that a few years ago
Answer:
so basically this is easy if you break it down
Step-by-step explanation:
the triangle area= 5x4/2= 20/2= 10
there are 4 triangles so 10 x 4=40
square area= 5x5= 25
40+25= 65units^2
