Measurement unit test part 1
Find the sum of a parallelogram with the base b and height h b equals 87 CM h equals 18.6 cm
1602.2 cm^2
what is the "sum" of a parallelogram?
To find the sum of the parallelogram with base b and height h, you need to use the formula:
Sum = base x height
Given that b = 87 cm and h = 18.6 cm, you can calculate the sum:
Sum = 87 cm x 18.6 cm
Now, multiply the values:
Sum = 1618.2 cm²
Therefore, the sum of the parallelogram is 1618.2 cm².
To find the sum of a parallelogram, we need to multiply the base (b) by the height (h).
In this case, the base (b) is 87 cm and the height (h) is 18.6 cm.
To find the sum, we can use the formula: sum = base * height.
Substituting the values, we get:
sum = 87 cm * 18.6 cm
To multiply these two numbers, we multiply the digits and then add the exponents of the units.
87 cm * 18.6 cm = (8 * 18) cm^2 + (7 * 18.6) cm
The first part simplifies to:
8 * 18 = 144 cm^2
The second part simplifies to:
7 * 18.6 = 130.2 cm
Therefore, the sum of the parallelogram is:
sum = 144 cm^2 + 130.2 cm
To add these two values, we keep the same units and simply add the numbers:
sum = 144 cm^2 + 130.2 cm = 274.2 cm
So, the sum of the parallelogram with base (b) equals 87 cm and height (h) equals 18.6 cm is 274.2 cm.
