Find the area and perimeter of the figure below, explain and show work pls

area is 26.285cm² permiter is 28.565 cm

Step-by-step explanation:

area

so split the shape into smaller shapes

half- circle

area of a circle is πr^2 so πx4^2 is 12.57 so half this number to get area of a half- circle =6.285cm2

rectangle area = (2+4+2) x 1= 8cm2

triangle area is 1/2 base x height

so 1/2 8 X 3 = 4 x 3= 12 cm2

add them all up 6.285 + 8 + 12= 26.285cm2

perimeter

do it bit by bit again

perimeter of half circle

for full circle =2πr^2 so = 25.13

for half circle= 12.565cm

rectangle part = 2+2+1+1 = 6cm

triangle part =5+5 = 10cm

total perimeter = 12.565+6+10= 28.565 cm

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
