7. A rectangle has an area of 45m2

Mathematics
1 answer:
ANTONII [103]3 years ago
4 0

Answer:

14 meters

Step-by-step explanation:

The area of a rectangle is given by

A = l*w

45 = l*9

Divide each side by 9

45/9 = 9l/9

5 =l

We want the sum of the length and width

w+l = 9+5  =14

Help with all of these please explain if u can !
sveticcg [70]

Answer:

1. 78cm^2

2. 200 ft^2

Step-by-step explanation:

1. i always cut these complex shapes into simpler ones (in this case a rectangle and a triangle)

the rectangles area is 6*8 or 48 and the triangles area is (10*6)/2 or 30 you then add the two areas to get the area for the whole shape 48+30=78

2. once again you're going to break this shape up into the individual rooms and then add them together the garage is a 4*6 room (24) the bedroom is a 8*4 room (32) the living room is a 10*10 room (100) the kitchens a  6*6 room (36) and the bathroom is a 4*2 room (8) you then add all these together

24+32+100+36+8=200
