In how many map squares did we spot more than 29 plant species
2 answers:
Answer:
10 map squares.
Step-by-step explanation:
We have been given a histogram, which represents the plant species spotted in the animal reserve.
The x-axis represents the number of plant species and y axis represents the number of map squares.
We can see that 0 to 9 species are spotted in 1 map square.
10 to 19 and 20 to 29 plant species are spotted in 2 map squares.
To find the number of map squares that spot more than 29 plant species, we will count number of map squares that spot 30 to 49 plant species as 30 to 49 numbers are more than 29.
We can see from our histogram that 4 map squares spot 30 to 39 plant species and 6 map squares spot 40 to 49 plant species.
Therefore, 10 map squares spot more than 29 plant species.

Area = 2831.25 square yards
Perimeter =215.6 yards
EXPLANATION
The area and perimeter of a rectangular field are found using the formula for finding the area and perimeter of a rectangle respectively.
That means, area of the rectangular field is given by the formula,
We just have to substitute
and 
into the given formula and evaluate.
This implies that;
This gives the area of the rectangular-shaped field to be;
square yards.
Now for the perimeter, we use the formula
Or
Substituting the values for the length and width gives,
Hence the perimeter of the rectangular shaped field is 215.6 yards.
Perimeter =215.6 yards
