Plz 25 points find the area of each figure to the nearest tenth.
a 140cm 110cm 180cm 50cm
b 8ft 8ft 10ft

Step-by-step explanation:

in "a" we need sides of the right triangle that form the right angle which are:

the common side with the rectangle is 140-50=90 cm

and the other side is 180-110=70 cm

the area of the right triangle is (90*70)/2=3150

and the area of the rectangle is 110*140=1540

and if you add them you get 18550 which is the overall area

in "b" you should use the Pythagorean theorem in the triangle ADE and find the side DE

the area of ADE triangle is:

(8*6)/2=24

the area of ABEC square is:

8*8=64

and if you add them both you get:

64+24=88

false

step-by-step explanation:

whenever we assume a point on a plane then according to geometry it will definitely have 2 dimensions and if it assumed in space then it will have 3 dimensions.
