7 cm
find the area.
a) 84 cm²
b) 84 cm
2.
2.5 m
1.8 m
2 m
find the area.
a) 5 m²
b) minnesota wild

Explanation:

Step1: Recall area formula for rectangle

The formula for the area of a rectangle is $A = l\times w$, where $l$ is the length and $w$ is the width.

Step2: Identify length and width for first - rectangle

For the rectangle with length $l = 12$ cm and width $w = 7$ cm, we substitute into the formula: $A=12\times7$.

Step3: Calculate the area of the first rectangle

$A = 84$ cm².

Step4: Recall area formula for parallelogram

The formula for the area of a parallelogram is $A = b\times h$, where $b$ is the base and $h$ is the height.

Step5: Identify base and height for parallelogram

For the parallelogram with base $b = 2.5$ m and height $h = 1.8$ m, we substitute into the formula: $A=2.5\times1.8$.

Step6: Calculate the area of the parallelogram

$A = 4.5$ m² (but this is not relevant to the options given for the parallelogram problem which has an incorrect option "Minnesota Wild").

Answer:

1. a) 84 cm²
2. There is an error in the options provided for the parallelogram problem as "Minnesota Wild" is not a valid measurement for area. If we ignore the wrong option, the area of the parallelogram is 4.5 m².
