Question

81 PTS !!!!!!!!!!!!!!!!!!!!!!!!!!! Great Mathematicians come on out here and help on problems 7 and 8!!! Warning Please actually help don’t write random irrelevant responses

Answer 1

here you just need to use scalling.

7)

in this case the we have to draw the area in bigger map with the scale of 3. This means, 1 unit in smaller map is now will be represented by 3 units in bigger map.

so 1 × 1 size box in smaller map = 3×3 size box in bigger map

as length and breadth both will be scaled to 3 times.

so original figure in smaller map it takes 6 square box of size 1×1

its going to take 54 square box of size 1×1.

please see image attached.

area in smaller map = 6 ×(1×1) = 6 square units

atea in bigger map for same = 6× ( 3×3) = 54 square units

8)

here we have to scale down the image.

that means 3 unit in bigger map will be now represented as 1 uNit in smaller map.

so length and breadth will be reduced to 1/3 in smaller map.

see image attached.

area in bigger map = 9×5 × (1×1) = 45 square units

area in smaller map = 9×5×(1/3 × 1/3) = 5 square units

excuse me for bad images and drawings
