81 pts ! great mathematicians come on out here and on problems 7 and ! warning actually don’t write random irrelevant responses

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
