They're the same because squares have 90 degree angles and that cut in half with a diagonal would make the angle acute at a 45 degree angle so depending on the lengths of the sides depends on the area, the angles have nothing to do with it because all squared have 4 right angles

What is the area of the shaded region <br> 1cm is in the middle
Archy [21]

Answer:

Area of the shaded region= 128.86\,cm^2

Step-by-step explanation:

Area of the shaded region=Area of the rectangle-Area of the circle

Area of rectangle= Length\times Width

Length=11\,cm\\Width=12\,cm

Area is:

           =11\times 12\\\\=132\,cm^2

Area of the circle = \pi \times r^2

r=1\,cm

As,        \pi =\dfrac{22}{7} =3.14

Area of the Circle is :

           =3.14\times 1 \times 1\\\\=3.14\times 1\\\\=3.14\,cm^2

Area of the Shaded region:

Area of the shaded region=132-3.14\\\\=128.86\,cm^2

19. If the scale is 1:100 on a plan, and a fence is 7,500 mm,
marshall27 [118]

Answer:

It will measure 75 millimetres on the plan.

Step-by-step explanation:

Given:

Scale on the plan = 1:100

Length of the fence =  7,500 mm

To find:

how many millimetres will it measure on the plan

Solution:

As the ratio on the plan is 1: 100, the for 7500 the ratio will

x : 7500

Now by cross multiplication we get

7500 \times 1 = x \times 100

7500 = 100x

x =\frac{ 7500}{100}

x = 75
