Please help me ill mark brainlyest if correct
Eva8 [605]

Answer:

50m²

Explanation:

first, we have to find the length and width of the backyard. since 4cm represents 5m, we know that the real width of the backyard is 5m.

as for the length of the backyard, 8cm is double of 4cm so we can also double 5m to get 10m.

now, we can find the area by taking 5m × 10m = <u>50m²</u>.

i hope this helps! :D
