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:
Step-by-step explanation:
The distance around the lot is the perimeter of the lot, which has a formula:
P 2L + 2W
We can fill in using the info given:
which multiplies to
and finding a common denominator:
and adding, gives you

The largest two digit number is 99 so, 1000 + 99 = 1099.
the ratio of two number 13/100=0.13
