(x + a) (x + b) = x² + (a + b) x + ab
75 * 77=
=(70+5)(70+7)
=70²+(5+7)*70+5*7
=4900+12*70+35
=4900+840+35
=5775
Answer:
Area = 64 cm²
Step-by-step explanation:
To find the area, we have to follow some steps:
=> <u>Step 1: Make the bases similar:</u>
Since we have 2 bases given 6 and 10 we have to come up with a third base by finding their average:
(6 + 10) / 2
(16) / 2
8
So now that we know our base,
=><u> Our second step is to multiply the base we found by the height of the trapezoid:</u>
Area = common base * height
Area = 8 * 8
Area = 64 cm²
