Find the surface area 7 cm
6 cm
12 cm
4 cm
A)210 cm^2
B)220 cm^2
C)230 cm^2
D)240 cm^2

The surface area is 240 cm^2

Step-by-step explanation:

The surface area is the sum of all the areas of the shapes present

we have two rectangles of measure 7 cm by 12 cm

A base rectangle of 4 cm by 12 cm

Two side triangles of base 4 cm and height 6 cm

Area of the rectangles is l * b

Area of the triangles is 1/2 * b * h

Thus, we have that;

(7 * 12) * 2 ) + 2 * (1/2 * 4 * 6) + (4 * 12)

= 168 + 24 + 48 = 240 cm^2

step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
