Well u could make a tree with the 2 numbers on top so one of the numbers on one tree and the other number on the other and then make a triangle so if the 2 numbers are 12 and 8 then you would put 8 on one and 12 on the other and then put a triangle under the 2 numbers and then lis the 2 numbers that multiply to get those answers so for 8 it would be 2 and 4 you would circle the 2 because it has nothing that can be multiplied to get it and keep going with 4 and get 2 and 2 and then circle the 2s then make a table and put the 2 2s in one column and then put the other 2 in another column then bring one number down from each column and multiply them together and you will get your answer if there are all different numbers then put them in all separate columns. Hope this helped!
Answer:
Step-by-step explanation:
To find the area of a rectangle you use the formula: A= lw
** l is length and w is width
For figure A and C, they're rectangles, so you multiply the length and the width to get the area:
Fig. A )A=lw
= (4)(4)
= 16
For figures B and D, you use the formula: A= bh/2
**B is the base and h is the height
Fig. D) A=bh/2
= 6(4)/2
= 12
Answer:
74 (square) cm
Step-by-step explanation:
First, to find the surface area of both faces, make each face into two right triangles.
Use the formula A = ab/2 to find the surface area of one of the new right triangles. in this case, A = 2x3.5/2 is equal to 3.5.
Double this to find the full surface area for each face, 7 (square) cm.
Next, find the surface area of the base by multiplying the length by the width. in this case, 4x5 = 20, your base surface area.
Next, find the surface areas of the sides the same way as the base. This example has the same measurements as well. 5x4 = 20.
Last, add all of the solutions together to get the surface are of the whole object. 7 + 7 + 20 + 20 + 20 = 74 (square) cm
