Answer:-15
Step-by-step explanation:
-4x/5=12
5x-4x/5=5x12
-4x=5x12
-4x=60
-4x/-4=60/-4
x=-15
Answer:82cm^2
Step-by-step explanation:
Area of shape=area of big rectangle + area of small rectangle
Length of big rectangle=10
Width of big rectangle=7
area=length x width
area of big rectangle=10x7
area of big rectangle=70
Length of small rectangle=4
Width of small rectangle=10-7=3
Area=length x width
area of small rectangle=4x3
area of small rectangle=12
Area of shape=70+12
Area of shape=82cm^2
Am assuming it is a rectangular garden
Area = length * width
851 = 23 * width
23* width = 851
width = 851/23
width = 37
width = 37 m.
