Answer:
Area: 120m²
Flowers: 600kg
Step-by-step explanation:
we can use Heron's formula to solve for the area.
Heron's formula:
Area of triangle = 
s = 1/2 (a+b+c)
s = 1/2 (10 +24+26)
s = 30
Area of triangle

Since every 1 m² of area can grow 5kg of flowers,
the yield of flowers will be:
120 x 5
=600kg
Answer:
Multiply the top equation by two because both y value will become opposites and will eliminate.

Answer:
Multiples of 8 are: 8, 16, 24, 32, 40, 48, 56
Step-by-step explanation:
V=LWH, W=L-3, H=5, V=270
L(L-3)5=270
5L^2-15L=270
5L^2-15L-270=0
L^2-3L-54=0
L^2+6L-9L-54=0
L(L+6)-9(L-6)=0
(L-9)(L+6)=0
Since L>0
L=9 meters
Given:
Length = 20 cm
Width = 4.5 cm
Height = 23 cm
To find:
Surface area of rectangular prism
Solution:
Surface area formula:
SA = length × width × height
= 20 × 4.5 × 23
= 2070
Surface area of cylinder is 2070 square centimeters.
