Answer:
54 sq units
Step-by-step explanation:
The triangle at the top (FAB) has a base of 10 and a height of 3. Area of triangle is 1/2bh so 1/2(10 * 3) = 1/2 * 30 = 15 sq units
If you cut off the triangle you have a trapezoid, EBCD. A trapezoid is (b1 + b2)/2 * h, so (6 + 7)/2 * 6 = 13/2 * 6 = 6.5 * 6 = 39 sq units
Add them together: 15 + 39 = 54 sq units
Answer:
the answers are the 1st and 2nd.
Step-by-step explanation:
It would matter if 4 is on the bottom then the sides are 5 and if 5 is on the bottom then the sides are 4. Look at the pic if you don't understand
Expression: 84 + 40
Here, Greatest Common Factor (GCF) of 84 & 40 is 4, so take it as a common factor:
= 4(21 + 10)
In short, Your Final Expression would be: 4(21 + 10)
Hope this helps!
